Wheelchairs - Part 9: Determination of Coefficient of Friction of Test Surfaces (Adopted ISO 7176-13:1989)More info
1ScopeThis part of ISO 7176 specifies a test method for determining the coefficient of friction of a test surface that has a rough texture, such as unfinished concrete. In the event that the test method is used for smooth or polished surfaces, care should be exercised that the coefficient of friction is measured as being constant over the whole area of the test surface.Several test procedures for wheelchairs, e.g. those specified in ISO 7176-1, ISO 7176-2, ISO 7176-3, ISO 7176-6 and ISO 7176-10, require that the coefficient of friction of the test surface be within specified limits.
